JOHN P. YV. PATILLO, OF CHICAGO, ILLINOIS.

WINDOW.

SPECIFICATIQN forming part of Letters Patent No. 683,183, dated September 24, 1901.

Application tiled July 23, 1900. Serial No. 24,509. (No model.)

To all wir/0m it may concern:

Be it known that I, JOHN BW. PATILLO, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Windows, of'which the following is a specification.

My invention relates particularly to an improvement in swinging windows, my object being to provide a window of improved construction which shall be simple, cheap, durable, and edective.

I accomplish my purpose by means of certain improvements in the connections between sash and suspending stiles and between suspending-stiles and pulley-Stiles, all as hereinafter fully described.

In the accompanying drawings, Figure l is a view in inner side elevation of a window embodying my improvements; Fig. 2, a plan section on line 2 of Fig. l; Fig. 8, a broken vertical section of the right-hand portion of the window, the section being as indicated at line 3 of Fig. 2 and the upper sash being removed; Fig. 4, a view of one of the righthand suspending-Stiles, and Fig. 5 a right edge view of a sash.

A represents the upper sash; B, the lower sash; C, the right-hand pulley-stile; D, the left-hand pulley-stile; E E, the outer windowstops; F F, the center stops; G G, the inner stops.; A and A2, the right and left hand suspending stiles, respectively, of the upper sash; B and B2, the right and left hand suspending stiles, respectively, of the lower sash; Aa and A4, the right and left sash-Stiles, respectively, of the upper sash g and BB and B4, the right and left sash-stiles, respectively, of the lower sash.

The stops E are provided at their faces adjacent to the suspending-Stiles A A2 with longitudinal grooves a. The stops F are pro- .vided at their faces adjacent to the same suspending-Stiles with grooves b and at their faces adjacent to the suspending-Stiles B B2 with tongues h. The suspending-Stiles B B2 are provided adjacent to the stops F with grooves for the tongues b', adjacent to the stops G with tongues c, and adjacent to the sash-Stiles B3 B4 with tongues c', tting grooves c2 in the sash-Stiles, and the stops G are provided adjacent to the stiles B' B2 with grooves for the reception of the tongues o.

The sash A is hinged to the suspendingstile A2 at the stile A4 by hinges d, and the sash B is similarly hinged to the sus endingstile B2 at the stile B4 by hinges e. he manner of connecting eachsash to its suspending-Stiles is the same. It may be added that each sash has tongue-and-groove connection with its suspending-Stiles and that the righthand suspending-Stiles are detachably connected with their sashes by locks of like construction, the lower locking device being clearly shown in Figs. 3 to 5, inclusive.

Each suspending-stile has attached to it in a suitable groove for housing the same a cord f, which passes over a pulley and is attached to a counterweight. pending-stile is supplied with a spring-held latch, comprising a vertical arm g, lying just in the rear of the tongue o in a recess in the stile, a horizontal arm g', lying in a horizontal recess g2, a laterally-projecting thumbpiece g3 on said horizontal arm, and an enlargement g4, affording a bearing for the spring employed. The latch is pivoted on a screw g5 at the lower end of the vertical arm. g6 is the spring, rmly secured to the suspending-stile at its lower end and bearing at its upper end against the enlargement g4. The horizontal arm g works beneath a recessed metallic plate g on the front faceof the suspending-stile and bridging the'recess g2, and its end projects (when the stiles are in registration) into a slot g8 in and beneath a metallic plate Q9 on the inner face ot' the sash-stile B3.

The pulley-stile C is provided with recesses h, (one only shown,) so located that when the sashes are elevated the recesses come opposite the elbows ofthe pivoted latches to permit the latter to be moved to unlock the suspendingstiles from the sash stiles. The springs g6 perform the double function of holding the latches and of taking up looseness between pulley-Stiles and suspendingstiles. The purpose of having the recesses h located in an elevated position is to prevent detachment of the suspending-stile when Each right-hand sus! IOO in a low position, whereby the counterweight, freed from the heavier weight of the window, might jerk the suspendingstile suddenly upward, with danger of snapping the cord.

The manner oi operating the window is to raise the bottom sash to the top of the window-frame, press upon the tl1u1nbpiece g3 to disengage the stile B' from the sash, and then lowerthe latter to the position shown in Fig. 3, the stile l' remainingin the position there shown. To permit the sash to Swingin wardly upon the hinges c tothe position shown in dotted lines in Fig. 2, the tongue c' at the stile B2 is beveled on the outer side, and in the construction shown the tongue c' on the stile B' is ont away at its lower end. if desired, felt or rubber may he employed to make the joints air and dust tight. In the construetion here shown the top sash is disconnected from its right-hand suspending-stile in precisely the same manner as ille lower sash, and the sash is lowered to the bottom of the window-frame and there swung on its hinges, while the lower sash is still open. After the upper window has been cleaned it is swung` shut and elevated to its proper position, where it is autoinatically locked to the suspendingstile. The lower window after being cleaned is then swung shut, elevated till. it beeomes automatically locked to its suspending-stile, and inally is lowered to its proper position, completing the operation.

The novel features of Construction :nay be employed either in connection with new windows or with old windows.

The details of construction may be varied withoutdeparture from myinvention. Hence I wish to be understood as intending no limitation by the particular description thereof except as shall appear from the appended claims.

eeaiee Vhat I claim as new, and desire to secure by Letters Patent, isl. In a window, the combination of a twosash frame, a sash, a suspending-stile, a lock on said stile engaging a part on said sash, and a recess at the upper portion of the frame for permitting said lock to be moved t0 free the suspending-stile from the sash, said frame being adapted to prevent movement of the lock except when the stile is in an elevated position, substantially as and for the purpose set forth.

2. In a window, the combination of a twosash frame having a pulley-stile provided at its upper portion with a slot, a sash, a suspending-stile, a lock carried by the stile engaging said sash and adapted to enter said slot when the stile is in an elevated position, and pivotal means for supporting the sash, su bstsiniially as and for the purpose set forth.

in a window, the combination with the frame, of a sash, a suspending-stile, pivotally joined to one vertical edge thereof, a suspendingstile at the opposite vertical edge provided wiih a loelerecess, a pivoted lockpieee carried by said last-named stile adapted to engage said recess, and a spring bearing against said lock-piece and against said frame, substantially as and for the purpose set forth. i

4C. In a window, the combination with a sash and a detachable suspendingstile of a lockpieee havinga vertical arm g pivotally oonnected to the stile, a horizontal arm g pr0- jecting into a recess in the sash, a thumbpiece on said horizontal arm, and a spring, substantially as and for the purpose set forth.
